INTERLOCKING-BLOCK WALL CONSTRUCTION.

Specification of Letters Patent.

Application'filed March 3, 1919. Serial No. 280,390.

T 0 all whom it may concern Be it known that I, SAM PrsororrA, a subject of the King of Italy, residing at Kansas City, in the-county of Jackson and State of Missouri, have invented certain new and useful Improvements in Interlocking-Block Wall Construction, of which the following is a specification.

This invention relates to interlockingblock wall construction, and has for its object to produce a construction possessing maximum strength and rigidity, and wind and waterproof properties. A further object is to produce a wall construction embodying the features of advantage or merit set forth, which can be erected quickly and economically. A'still further object is to produce a wall construction composed of blocks of such form that all joints, both Vertical and horizontal, are broken.

lVith these objects in view the invention consists in certain novel and useful features of construction and organization of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawing, in which: I j

Figure 1, is a perspective view of a corner of a wall embodying the invention.

Fig. 2, is a Vertical section taken on the line II II of Fig. 1. g V

Fig. 3, is a plan View of the first tier of blocks employed in the production of the corner shown by Fig. 1.

Fig. 4, is a perspective view of one of the corner blocks.

Fig. 5, is an inverted perspective view of one of the full size blocks used to form the jamb of a doorway, window 'or other opening in the wall.

Fig. 6, is a perspective view of one of the common or intermediate blocks of the wall.

In carrying out the invention it is desirable to state that the corner blocks are made in rights and lefts but otherwise are of identical construction. The jamb blocks are of identical construction except that in every other tier the blocks will be of half length, so that their unbroken or jamb ends may be flush as indicated in Fig. 1, and the ordinary or inte mediate blocks are of identical construction. and it will be understood that the blocks may be made of cement, clay or any v other suitable material and may be either molded or otherwise produced.

Referring first to the intermediate blocks, it will be seen that each comprises similar side portions 1 of oblong rectangular form and a central portion 2 of the same form and sire as portions 1 but disposed out of register with the latter so as to produce in effect an lnverted L-shaped rib projecting upward beyond the side portions land beyond one end of said side portions, so as to produce a horizontal grooveB and a vertical groove 4 between the side portions, and, in the preferred construction, the lower half of the rib where the same projects beyond the end of the sides is widened to produce a dove-tailshaped portlon 5, and the vertical groove 4 at the opposite end of the block; is likewise widened to dove-tail form as at 6 for the reception of the dove-tail portion 5 of the adjacent block of the same tier, as shown most clearly by Figs. 2 and 3.

Each jamb block whether of the full or half length size comprises side portions 7 corresponding to side portions 1 and an L- shaped rib 8 corresponding to rib 2 so as to form a horizontal groove 9 corresponding to groove 3 except that it does not extend through the full length of the block and thus leaves the jamb face of the block solid or unbroken where in the common or intermediate type of block there appears the vertical groove 4.

' The lower portion of the vertical part of the rib 8, is widened to form a dove-tail portion 10 corresponding to the dove-tailportion 5 of the common or intermediate type of block.

In Fig. 4, which shows a perspective view of one of the corner blocks, hereinafter identified respectively as right and left hand blocks a and b, 11 indicates the sides and 12 the rib, which in this instance terminates short of both ends of the sides so as to leave atone end thereof a vertical groove 13 corresponding'to grooves 4, and widened as at 14 to dove-tail form. At the other end, the rib is reduced in width by forming a vertical recess 15 therein and at such end the inner side portion 1 is bifurcated to produce a vertical groove 16 which is widened to dovetail form as at 17 for the reception of the dove-tail portion 5, of one of the common or intermediate types of blocks.

In the corner section of the wall indicated. it will be seen that of the ground tier of blocks there is one corner block a which over- Patented Aug. 24, 1920.

laps the end of the adjacent common or intermediate block extending at right angles thereto, and that the end portion of the rib of such abutting common or intermediate 5 block projects into the laterally facing groove 16 of said block a, it being noted by reference to Fig. 3, that the dove-tail form of said groove 16 and of the engaging portion of the rib 2 of the said abutting block,

guards against any possibility of said blocks being separated except by lifting one of them vertically, which statement applies to all of the blocks employed in the construction of the wall where the dove-tailrelation obtains, and in this connectionit is desirable to state that for all main or external Walls this dove-tail relation is contemplated,but that for partition or internal walls the dovetailing of the blocks is not indispensable. It will also be noticed that the outer end of the rib 2 fits-in the vertical recess 15 formed in the ribjl2 of said block a.

The common or intermediate block 1 juxtaposed to the block 1 abutting against.

the said corner block a has the verticalportion of its rib 2 fitting with a dove-tail relation in the vertical groove 4 of the said block abutting'aga'inst the said corner block,-and this relation of parts will obtain with all of the remaining common or intermediate blocks. The groove 13in the outer end of the block a, will likewise receive the vertical portion of the rib 8 of a full length jamb block, or of an intermediate block according to the distance which it is desired to locate a door opening or the like from the said corner block a.

From the above description the completion'of the lower tier will be obvious. F or the second tier, a left hand corner block b is placed upon and at right angles to corner block a, and overlaps half of the underlying intermediate block, it being obvious that the horizontal groove 18 in the underside of block '6 receives the upper portion ofthe rib 2 of the underlying intermediate block, and that the lateral groove 16 of block b-is adapted for the reception of the end portion of the abutting intermediate'block of the second tier of the wall of which block 01 forms a portion of the side, it being-also noticedthat the intermediate block lastreferred to overlies and rests upon the jamb block 7 and receives in its horizontal groove 55 3, the upper portion of the rib 8 of said jamb block 7, it being likewise noted that the outer end portion of the rib 2 of the said intermediate block 1-, engages the recess 15, in the outer end of the rib 12 of corner block b, and that the vertical groove 4: in the opposite end of the said intermediate block, receives the end portion of the rib 8 of the half-length ambblock resting upon the jambblock of the undermost tier, and that part ofthe upper portion of the rib of the last named block will engage the horizontal roove 9 in the underside of the half-length amb block 7.

The arrangement of the third tier of blocks will correspond to that of the lowest tier of blocks, and the arrangement of the fourth tier will correspond to that of the second tier, and so on, and it will likewise be understood that the arrangement at the corners will be as described.

It will thus be seen that the blocks are arranged inbreak-joint relation both vertically and horizontally, and are so interlocked that pressure applied laterally a ainst any block of a wall is resisted by all 0% the. blocks of said Wall, and this interlocked relation is made more secure where they are dove-tailed together, as this guards against any possibility of independent endwise sliding movement of any block; It will also be'app'arent that by this double breakjoint relatlon ofthe blocks 'wind and rain are excluded, but that the joints may be made absolutely impervious to wind and rain by theuse of a liquid binder of any suitable character which may be applied if desired to the ribs and walls of the grooves by means of a brush or otherwise.

From the above description it will be apparent that I have produced a wall construction which embodies the features of advantage set forth as desirable in the statement of the object of the invention, and which is obviously susceptible of modification in minor particulars without departing from the principle of construction involved or sacrificing any of the advantages of the appended claims.

I claim:

1. A corner block for a wall, having a groove in one end and a groove in one side near the opposite end, and also having a central longitudinal groove in the lower'face and an upwardy -'projecting longitudinal rib at the upper side, said rib having a vertical recess registering with the said side groove.

2. A corner block for a wall, having a groove in one" end and a'groove in one side near the opposite end, and also having a central longitudinal groove in the lower face and an upwardly -projecting longitudinal rib atthe upper side, said rib having a vertical recess registering with the said side groove, in combination with a block lying 12 in the same horizontal plane as said corner block and abutting at one end, the side of the corner block and provided with a rib engaging the side groove of said block and the recess of the upwardly-projecting rib thereof.

3. A corner block for a wall, having a groove in one end and a groove in one side near the opposite end, and also having a central longitudinal groove in the lower face and an upwardlyprojecting longitudinal rib at the upper side, said rib having a vertical recess registering with the said side groove, in combination with a block lying in the same horizontal plane as said corner block and abutting at one end, the side of the corner block and provided with a rib engaging the side groove of said block and the recess of the upwardly-projecting rib thereof, and a block also occupying the same horizontal plane as said corner block and abutting endwise against the same and extending in the same direction; said last named abutting block having an end rib engaging the end groove in said corner block, the upper edge of said rib lying in the same horizontal plane as the upper edge of the upwardlyprojecting rib of said c0rner block.

In testimony whereof l aflix my signature.

SAM PISGIOTTA.
